Luminous Egress Path Markings help you find your way out from American PERMALIGHT Inc

During the 9/11 events, PERMALIGHT® photoluminescent markings helped evacuate the New York City World Trade Center Tower stair cases. The NIST evacuation study results led to photoluminescent exit path marking requirements in NYC high rise office building staircases, and now the 2009 IBC/IFC Codes and NFPA101-Life Safety Code.
